Extravagant Replication + Walk the Aeons + Pinnacle Monk // Mystic Peak

Extravagant Replication

Walk the Aeons

Pinnacle Monk // Mystic Peak

How it works

1. Cast Walk the Aeons by paying its mana cost, causing you to take an extra turn after this one.
2. Move to your next turn.
3. At the beginning of your upkeep, Extravagant Replication triggers, creating a token copy of Pinnacle Monk
4. When the Pinnacle Monk token enters the battlefield, it triggers, returning Walk the Aeons from your graveyard to your hand.
5. Repeat.

This elegant engine achieves infinite turns by recycling a single copy of Walk the Aeons each upkeep. The process is powered by Extravagant Replication, which dutifully churns out a fresh token copy of Pinnacle Monk (playing as Pinnacle Peak when needed) at the start of every turn. Whenever that token enters the battlefield, its triggered ability reaches into your graveyard to retrieve Walk the Aeons, leaving you ready to cast it again and take all the time you need.
